Struct ThrownError 

pub struct ThrownError {
    pub message: String,
    pub backtrace: Option<WasmBacktrace>,
    pub denial: Option<Denial>,
}

An uncaught thrown Error, carrying its name: message text plus the throw-site backtrace the engine attached to the escaped exception; uncaught_error re-wraps both here so render prints a source backtrace like a trap.

Fields

message: String

backtrace: Option<WasmBacktrace>

denial: Option<Denial>

Set when the escaped error is a denial the runtime itself threw, as opposed to a PermissionDeniedError the program constructed.
